Electrostatic Discharge

To prevent damaging the system, be aware of the precautions you must follow when setting
up the system or handling parts. A discharge of static electricity from a finger or other
conductor can damage system boards or other static-sensitive devices. This type of damage
can reduce the life expectancy of the device.

To prevent electrostatic damage, observe the following precautions:

Avoid hand contact by transporting and storing products in static-safe containers.

Keep electrostatic-sensitive parts in their containers until they arrive at static-free
workstations.

Place parts on a grounded surface before removing them from their containers.

Avoid touching pins, leads, or circuitry.

Be sure you are properly grounded when touching a static-sensitive component or
assembly.

Grounding Methods

There are several methods for grounding. Use one or more of the following methods when
handling or installing electrostatic-sensitive parts:

Use a wrist strap connected by a ground cord to a grounded workstation or computer
chassis. Wrist straps are flexible straps with a minimum of 1 megohm

±

10 percent

resistance in the ground cords. To provide proper ground, wear the strap snug against the
skin.

Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on
both feet when standing on conductive floors or dissipating floor mats.

Use conductive field service tools.

Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized
HP reseller install the part.

IMPORTANT: For more information on static electricity, or assistance with product installation, contact
your authorized HP reseller.
